Downloading NCBI genomes from a given taxonomy

The Entrez Direct toolkit is great for programmatic access to all of NCBI’s resources. This little snippet below finds all of the refseq representative genomes for a given NCBI taxonomy ID, makes a little summary of the genomes downloaded and uses wget to download the genbank files from the Assembly FTP. Change the inital query in the first call to esearch to change what genomes are downloaded.
